Get linux-integration tests work with tox

[FrankK-1234]

Hello,

I want to share some things as it might be helpful for other newbees. 'What did I do to get the tox 3.12-linux-integration-{py-amqp,kafka} to pass'?

The error

Running tox failed with in 3.12-linux-integration.py-amqp|kafka:

  File "/home/$$$/Projecten/kombu/.tox/.tox/lib/python3.12/site-packages/docker/transport/unixconn.py", line 27, in connect
    sock.connect(self.unix_socket)
FileNotFoundError: [Errno 2] No such file or directory

Other messages

I also saw the following message at the start:

ROOT: will run in automatically provisioned tox, host /usr/bin/python is missing [requires (has)]: tox-docker>=3.0
ROOT: install_deps> python -I -m pip install tox 'tox-docker>=3.0'
ROOT: provision> .tox/.tox/bin/python -m tox

Using 'pip install tox-docker' removed the message but did not resolve the issue.

Checking docker

• Make sure I had docker installed, see

• And started: systemctl start docker

• Rerunning tox. The error changed into permission denied

• The resolution: add group docker to my user account: sudo gpasswd -a $USER docker (logout/in)

• Now tox was starting the docker images:

  3.12-linux-integration-py-amqp: docker> run 'rabbitmq' (from 'rabbitmq')
  3.12-linux-integration-py-amqp: docker> health check 'rabbitmq' (from 'rabbitmq')
  

Workaround for missing python-xdist

However it failed on pytest with:

3.12-linux-integration-py-amqp: commands[0]> pytest -xv -E py-amqp t/integration -n2
ERROR: usage: pytest [options] [file_or_dir] [file_or_dir] [...]
pytest: error: unrecognized arguments: -n2
  inifile: /home/$$$/Projecten/kombu/setup.cfg
  rootdir: /home/$$$/Projecten/kombu

I think this could be resolved by installing python-xdist which implements the -n parameter. However i used a workaround to call tox with empty arguments: tox -- for me that did the trick.

Sumarizing

• install tox-docker
• intsall, start and allow docker
• run with tox --

Not sure if these are official methods, but for me it worked and it finally gave me the message:
congratulations :) (465.25 seconds)

I could not find real guidelines so please let me know if these were the right steps to follow.

Regards,

Frank
